Abstract

The invention provides a plug bush which is firmly contacted with pins of a power plug, has large contact area and great current capacity and is used for domestic use, etc. An upper end of a slot wallof a U-shaped slot plug bush is sequentially extended and bent towards the inside of the plug bush to form an elastic contact piece, an elastic support piece, a support arm, an auxiliary supporting piece and an inclined support arm. When the plug bush is completely tabled with the pin, the support arm, the auxiliary support piece and the inclined support arm to form a firm A-frame which is supported among slot walls to push the pin to have close surface contact with the plug bush, that is, a firm maximized permanent clamping force is formed, and the clamping force is never weakened or lost, and the serious dependence of the clamping force of the plug bush on property, thickness and elasticity of a sheet metal is overcome. The plug bush with the shape and the structure has the advantages of large current capacity, safe use and long service life.

Description

Technical field

[0001] The present invention relates to a power socket for household and similar uses, the power socket socket has a maximum permanent clamping force. Background technique

[0002] The national standard stipulates that the pins on the power plugs for household and similar purposes are flat, and the pins on the power plugs for household and similar purposes in many countries in the world are mostly flat. But it is unreasonable. The shape and structure of the socket is mostly a simple "U"-shaped groove that tightens the neck. When the plug is inserted into the power socket, it often appears: first, the contact between the socket and the pin is a line contact, and the contact area is very small, resulting in The flow capacity is small; the second is that the clamping pin of the socket is only clamped by the mechanical elasticity of the socket, the clamping force is small, and the contact is not firm; the third is that the plug is inserted in the power socket for...
